To all who/n it m my concern Be it known that l. .\l)0l.l" Ihfll'l'SCIUIANN. a suhjeet ottlle l'hnperor of Germany, residing at llltrille-on-tlie-Rhine, (iernnurv. hare invented ltuproretuents in \Vindow-Frames. ot' whieh the 'lollowiug is a speeitieation.

The present invention relates to lranies sueh as used for windows. doors and the like.

and more parlieularly to the t \'pe ol L'ltt 't'ranies used in gardens and the like l'or the proteetion and foreiug' of plants. lt known to make sueh t'rames either of iron or wood. The iron l'rames have the advantage of being durable. hut the are at the same time heavy and. being {,ftunl heat-eonduetors. they tend to maintain a unil'orlu temperature at both sides of the l'raine. The wooden frames are light and tll tl had heat-eonduetors. but are detrimentally att'eeted by moisture and therefore ol little durability.

for the reeeption of a wooden mass.

Aeeording to the present invention the frame is made ol solid wooden laths onto which a jacket of metal plate is lightly pressed. 4

The invention is illustrated in the aeeolnpanying drawings by a perspeetive erossseetional view of a lath such as used for plant protecting frames.

The frame is made of solid wooden laths 7) onto whieh a jaeket (L of galvanized ironplate is pressed so as to tit tightly on the wood and prevent aeeess of air and moisture to the same. At the side or sides of Specification of Letters Patent.

It is also ltnowntomalte l'rame out of metal plate formed With a ehannel Patented Mar. 26, 1912.

t the lath adjoining the glass panes (I, the metal plate is bent to form a ledge g for supporting the. panes. The edges 0 of the metal plate are joined and lapped, the scam I twine disposed near the ledge 1 so as to be eorered hy the putty f used for seeuring the panes to the frame. In this manner a loosening of the seam as well as an entrance through the seam of moisture. will l|e:.ef t'et-tively prevented hy the putty. The hpk per surl'aees ol the laths are preferably ehanneled. as shown in the figure, sueh ehtmnelin; MIYlHfJ on the one hand to strengthen the frame and on the other handto pro- \ide means for eolleetine and discharging the water during showers ol rain.

.\ l'raine eonstrueted in this manner will he both light and strong". It will also he of great durahilitv sinee the wood is proteeled hy the plate jaeltetagainst moisture. .\t the same time the frame has a low degree of heat-eoinluetirity and does not therefore tend to equalixe'the temperatures prevailing: at the opposite sides thereot'.

Window and like frames eomposed of wooden laths covered entirely by metal plate, said plates l ein; bent to form ledges for the reeeption ot' the glass panes, the edges ot the plate being lapped. the seam being disposed so as to he eorered hy the putty whieh seeures the panes to the tranie, substantially as set lorth.
